The Excellence of Shaking Hands When Greeting Someone
وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَبَّلَ النَّبِيَّ،صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ الْحَسَنُ بْنُ على، رَضِيَ اللَّه عَنْهُمَا، فَقَالَ الأَقْرَعُ بْنُ حَابِسٍ: إِنَّ لِي عَشَرَةً مِنَ الْوَلَدِ مَا قَبَّلْتُ مِنْهُمْ أَحَدًا. فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ : مَنْ لاَ يَرْحَمُ لاَ يُرْحَمُ! ((مُتَّفَقٌ عَلَيْهِ))
Abu Hurairah (May Allah be pleased with him) reported: The Prophet (ﷺ) kissed his grandson Hasan bin 'Ali in the presence of Aqra' bin Habis. Thereupon Aqra' remarked: "I have ten children and I have never kissed any one of them." The Messenger of Allah (ﷺ) cast a glance upon him and said, "He who does not show mercy to others, will not be shown mercy." [Al-Bukhari and Muslim].
